Viruses that infect bacteria, multiply and cause their lysis, are called

  1. lysozymes
  2. lytic
  3. lipolytic
  4. lysogenic
Correct Answer: Option(b)
Solution: When bacteriopbhage infects a bacterium, it entirely depends on the host for its multiplication. It utilises the host machinery for replication and producea large number of progeny (phage prticles). The bacterium cell undergoes lysis and dies to liberate a large number of these phage paricles which are ready to start another cycle by infecting new bacterial cell. This cycle is known as lytic cycle.
